In large parts of Europe and North America, the decline in industrial emissions over the past 20 years has reduced pollution of the atmosphere and in turn of soils and water in many natural areas. The fact that this positive development can also have negative implications for these regions has been demonstrated by scientists at the Helmholtz Centre for Environmental Research (UFZ) in the journal Global Change Biology. According to their findings, declining nitrate concentrations in the riparian soils surrounding the tributary streams of reservoirs are responsible for the increasing release of dissolved organic carbon (DOC) and phosphate and a deterioration in water quality. In the case of drinking water reservoirs this can cause considerable problems with respect to water treatment.

Los estómagos del ganado, la fermentación en los campos de arroz, el fracking para el gas natural, las minas de carbón, las turberas, los bosques en llamas…todos ellos producen metano, el segundo gas de efecto invernadero más importante, después del dióxido de carbono. ¿Pero cuánto? ¿Y cómo podemos reducir estas emisiones? ¿Y está el fracking por freír al planeta, o son las emisiones de bovinos quienes tienen la culpa?

It turns out bird poop helps cool the Arctic.

That’s according to new research from Colorado State University atmospheric scientists, who are working to better understand key components of Arctic climate systems.

Climate change is one of the most serious threats facing the world today. With the effectuation of the Paris Agreement, there has been a rising interest on carbon capture and utilization (CCU).

A new study, led by Professor Jae Sung Lee of Energy and Chemical Engineering at UNIST uncovers new ways to make biofuel from carbon dioxide (CO2), the most troublesome greenhouse gas. In their paper published in the journal Applied Catalysis B: Environmental, the team presented direct CO2 conversion to liquid transportation fuels by reacting with renewable hydrogen (H2) generated by solar water splitting.

Los estadounidenses desechan cerca de 12,8 millones de toneladas de productos textiles anualmente, es decir, casi 40 kilos por cada hombre, mujer y niño. En los Estados Unidos y en todo el mundo, un número creciente de ecologistas y directivos de la industria textil coinciden en que ha llegado el momento de poner fin a la cultura del desperdicio textil y están empezando a fabricar a gran escala nuevas prendas de vestir elaboradas con material usado.
